WRAPPER.

Application filed June 16 To all whom it may concern Be it known that I,LAWRENCE D. Mon- TON, a citizen of the United States of-America,residing at Sandusky, in the county of Erie and State of Ohio, haveinvented certain new and useful Improvements in lVrappers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to wrappers designed for use in forming aprotective package for the shipment of articles, and having particularreference to a construction suitable for the shipment of incandescentelectric lamp bulbs. Heretofore various devices have been employed forthe protection of lamp bulbs, but none have been altogethersatisfactory. The difiiculty encountered is the protection of the tip,which is so fragile that a slight impact will break it, thus destroyingthe vacuum and rendering the lamp useless. With the present inventionthis difiiculty is overcome by a construction which holds the bulb frommovement within the Wrapper, while the latter projects sufficientlybeyond the tip end of the bulb to effectively protect it.

In the drawings: Figure 1 is a perspective view of the wrapper beforeapplication; Fig. 2 is a cross section showing the manner ;of wrappingthe bulb; Fig. 3 is a longitudinal section through the wrapper with thebulb therein; and Fig. 4 is a view similar to Fig. 1 showing a modifiedconstruction.

The type of wrapper most commonly used in the shipment of incandescentlamp bulbs is a longitudinally corrugated paper tube, so proportionedin. diameter to the lamp bulbthat the corrugations are drawn out or 40expanded at the edge diameter of the bulb, forming a double taperingpackage. This in'a measure holds the bulb from-longitudinaldisplacement, but, due to the stretch-, ing 'out of the corrugations,there is frevquently sufficient displacement to break the *tips. Withthe present construction, the

' ':'advantages of the corrugated tube wrapper -iare retained, while inaddition thereto pro:

.vision "is made for absolutely holding the '50.

bulbs ifrom' displacement, in the following '-;manner AL-is a sheet ofcorrugated board, having a-non-corrugated'single facing B. [The width.of the blankfis such that when q wrapped around the bulb the oppositeedges will. meet, and these are then securedto- Specification of LettersPatent.

getl 1er by a gummed flap C, preferably a prruectmg portion of a papercover D which eXtends the entire area of the blank. The paper cover D isof greater length than the faced corrugated board, and consequentlyafter the wrapper is in cylindrical form, these projecting ends of thepaper may be tucked in to form a cushion E at the end of the bulb. Ifthe wrapper, as above described, were made of the diameter of the sizeof the largest dimension of the bulb, there would still be thepossibility of longitudinal displacement of the bulb, which might resultin breaking the tip. I therefore provide retaining shoulders forengaging the convex portion of the bulb on opposite sides of the portionof greatest diameter, preferably by crushing down the corrugations asindicated at G. These crushed-down corrugations G form a groove in theblank, and

the width of the latter is such that when wrapped around the bulb withits largest diameter in. the groove, the opposite edges of the blankwill meet. Thus the diameter of the uncrushed portions of thecorrugations is less than the maximum diameter of the bulb, andconsequently opposed shoulders are formed, which hold the bulb fromlongitudinal movement.

In Fig. 4, a modified construction is shown, in which, instead ofcrushing down the corrugations, the latter are cut away at a number ofpoints H to form retaining seats for the bulb. This will produce thesame effect of holding the bulb from longitudinal movement, and it isobvious that various other modifications might be made to produce asimilar result.

When the wrapper is applied to the bulb and the ends of the paper covertucked in, the result is a cylindrical package, which is easily packedwithin an outer case and which forms an absolute protection, not onlyfor the body of the bulb but also the tip thereof.

What I claim as my invention is:

1. A wrapper for tipped bulbular bodies. comprising a blank ofcorrugated board having a paper cover of greater dimensions, with anadhesive portion, said blank having concave depressions formed in aportion of the corrugations to receive the maximum diameter of the bulbwhen said wrapper is wrapped thereabout, said adhesive portion forming ameans of uniting the edges of the blank, and the projecting portions ofthe cover being adapted to be tucked in the ends of the wrapper to formcushions for the bulb.

A wrapper for tipped bulbular bodies, comprising a corrugated blankhaving concave depressions formed in a portion of the corrugations toreceive the maximum diameter of the bulb when said Wrapper is wrappedthereabout, said blank having projecting portions adapted to be tuckedin the ends of the Wrapper to form cushions for the bulb,

A wrapper for bulbular bodies having a maximum diameter intermediateportions of lesser diameter, comprising" a corrugated blank havingconcave depressions formed in a portion of the corrugations to receivethe maximum diameter of the bulb When the Wrapper is secured thereabout,and adapted to hold said bulb from movement by engaging the portionsupon opposite sides of the maximum diameter of the bulb.

In testimony whereof I affix my signature in presence of two Witnesses.
